LASTING MACHINE Filed July 15, 1932 g- WVE/VTUFK Patented Mar. 13, 1934 NT FFHC LASTING MACHINE Fred Ricks, Leicester, England, assignor to United Shoe Machinery Qorporation, Paterson, N. J., a corporation of New Jersey Application July 15, 1932, Serial No. 622,706 In Great Britain August 25, 1931 11 Claims.

This invention relates to lasting machines and more particularly to shoe-end lasting means. The invention is herein illustrated as applied to means for lasting the heel ends of shoes in a machine of the character disclosed. in a copending application of Joseph Gouldbourn, Fred Ricks and William T. B. Roberts, Serial No. 621,856, filed on July 11, 1932, but it is to be understood that it is not limited to machines of that particular type nor to heel-end lasting means.

An object of the invention is to provide improvements in end-lasting wipers such as to permit the operation of the wipers to be extended farther along the sides of some kinds of shoes than has been practicable heretofore, for example, forwardly beyond the heel breast ine upon the shank portion of the shoe bottom in the heel-end lasting operation, without danger of damage to the shoe materials. For the purpose in view the invention provides a novel wiper construction including wiping members that are yieldable in response to pressure of the upper thereon in the wiping operation, the wipers herein shown being provided at the ends thereof that are farthest from the end face of the shoe with spring-controlled wiping members that are yieldable heightwise of the shoe relatively to the other upper-engaging portions of the wipers. The wipers may accordingly be so extended as to operate on portions of the bottom of a shoe where the rear endsof a lip or rib on the insole are located without danger of damage to the lip or rib in wiping the upper inwardly over the insole, or to operate without damage forwardly of the heel seat on a shoe having an unlipped insoie but in which there is a high-arched formation of the shank portion of the shoe bottom beginning close to the heel seat, as in some womens shoes that are provided with high heels. As herein illustrated the yieldable wiping members are mounted on end portions of the wipers that are detachable to vary the distances that the wipers extend along the sides of the shoe for operating on shoes of different sizes, as disclosed and claimed in Letters Patent No. 1,886,279, granted on November 1, 1%)32 upon an application of Reginald B. Woodcock and Harold Lane. In accordance also with that disclosure the wipers herein shown are provided with openings through which fastenings are driven to fasten the upper in lasted position, and as illustrated the yieldable wiping members have openings therein to permit the driving of such fastenings into portions of the shoe bottom upon which they operate, the fastenings being driven from pockets provided in the detachable wiper end portions.

The novel features of the invention, including various novel details of construction and comm binations of parts, will now be more particularly described by reference to the accompanying drawing and pointed out in the claims.

In the drawing,

Fig. l is a view partly in plan and partly in section showing end-lasting wipers constructed in accordance with this invention;

Figs. 2 and 3 show, in front and side elevation, respectively, a detachable wiper end portion shown in plan at the right-hand side of Fig. 4 and provided with a yieldable wiping memher for purposes of the invention, the construction being such as to permit the driving of two fastenings through this member; and

Figs. 4, 5 and 6 are, respectively, front, plan and side views of a detachable wiper end portion having a yieldable wiping member constructed for the driving of only one fastening through it, these figures showing the end portion which is constructed for use on the lefthand wiper shown in Fig. l.

The wipers illustrated comprise a pair of blocks 10 formed to extend around the heel end of a shoe, one of these blocks being shown in section in Fig. l. The blocks 10 are fastened to plates 12 which have integral with them portions 14.- extending upwardly and forwardly over the blocks 10, as more fully disclosed in the first above-mentioned application. The blocks 10 and the plates 12 may be considered inclusively as the wipers, and as also more fully disclosed in the first-mentioned application are, in the lasting machine, mounted for advancing movement lengthwise of the shoe and for swinging or closing movements laterally of the shoe each about an axis extending heightwise of the shoe and located substantially at the meeting point of the blocks 10. Formed in the blocks 10 are tack pockets of passages 16 from which tacks are driven into the shoe bottom to fasten the upper in lasted position, each tack pocket having associated therewith a ball 18 to support the tack in position to be driven, the ball being controlled by a leaf spring 20 which presses it inwardly. It will be understood that when the tack is driven the spring 20 yields to permit the tack head and the driver (not shown) to pass. The extensions 14 of the plates 12 are provided with passages 22 in alinement with the pockets 16 and in which the drivers are mov- 1 able, and also with passages 24 through which tacks are fed to the tack pockets.

Each of the blocks 10 in the construction herein shown has in it nine tack pockets 16, and at the front end of each block there is fastened to the extension 14 of the plate 12 a readily detachable end piece which serves as a continuation of the block 10 and has in it one or more tack pockets and one or more tack supply passages, these detachable end pieces being provided to adapt the machine better for use on shoes of the larger sizes, as disclosed in Letters Patent No. 1,886,279. In Figs. 1, 2 and 3.and Figs. 4, 5 and 6, respectively, there are illustrated detachable end pieces differently constructed for use on shoes of different kinds or sizes. The end piece shown in Figs. 1, 2 and 3 comprises a block 26 fixed by a screw 28 and a dowel pin 30 to the extension 14 of the right-hand plate 12, and it will be understood that a similar end piece, shown in section in Fig. 1, is secured to the extension of the left-hand plate. Each block 26 is buttressed from above by a face 32 on the extension 14 and at its outer side by a face 34 on the same extension, so that it is effectively supported against the upward and outward pressure of the shoe upon it as it is moved inwardly over the shoe bottom. "Each block 26 has in it two tack pockets 36 similar to the tack pockets 16 in the block 10, and also tack retaining balls 38.and springs 40 corresponding to the balls 18 and springs 20 on the block 10, together with suitable passages through which the tacks are fed to the tack pockets from openings 24 in the extension 14 of the plate 12.

For purposes of this invention each block 26 has mounted on it a-member 42 which is the actual shoe-engaging or wiping member and through openings 44 in which two tacks are driven from the corresponding tack pockets 36. The member 42 has projecting upwardly from it a stem 46 slidingly mounted in the'block 26, and a spring 48 mounted in a bore in the block and engaging the member 42 presses the member downwardly. Downward movement of the member 42 is limited by a pin 50 which is fixed in the block 26 and is engaged by a shoulder on the stem 46.

In Figs. 4, 5 and 6 there is shown a detachable end piece or block 52 provided with a yieldable upper-engaging or wiping member 54 similar to the member 42 of the block 26 but of smaller size, considered with reference to its extent lengthwise of the edge of the shoe bottom, the block 52 and member 54 being constructed for the driving of only one tack instead of two. That is, the block is provided with a single tack passage or pocket 56, ball 58 and spring 60 performing the functions of corresponding parts shownin Figs. 2 and 3, and the member 54 has a single opening 62 through which the tack is driven. Each block 52 can be fixed to the po tion 14 of thecorresponding plate 12 by the same screw 28 and dowel pin 30 as when the block 26 is used. The wipingrmember 54 has a stem 64 guided in the block 52, and this stem has in it-a bore 66 to receive the endmost driver of the group of eleven drivers associated with the corresponding wiper. When the block 52 is in use this endmost driver is inoperative to drive tacks-but in view of the provision of the bore 66 to receive it, it need not be removed from the machine unless desired. A spring 68 forces the member 54downwardly, its downward. movement being limited by a pin '70 engaged by a shoulder on the stem 64.

The use of end pieces having yieldable wiping members, as above described, is of particular advantage as permitting the wiping operation to be extended somewhat forwardly of the heel seat on certain kinds of shoes without damage to the shoe materials. In operating, for example, upon a shoe of the welt type which, at the time of the heel seat lasting operation, has unlasted upper material adjacent to the front end of the heel seat where the rear ends of the insole lip or rib are located, the yielding wiping members 42 or 54, each of which has a rounded inner edge, may be used to wipe this unlasted portion of the upper over the lip or rib without damage to the latter because of the provision for yield of the members heightwise of the shoe in response to pressure of the upper thereon. Similarly the wiping action may be extended forwardly. of the heel seat without damage on shoes having unlipped insoles but in which there is a high-arched formation of the shank portion of the shoe bottom beginning close to the heel .seat, as in some womens shoes of the McKay type which are provided with high heels. In this case the yieldable wiping members, which have rounded forward edges as well as rounded inner edges, will act yieldingly to wipe the upper inwardly on the arched portion of the shoe bottom without any damage. In operating on shoes having lipped or ribbed insoles tacks will not usually be required to hold portions of the upper upon which the yieldable members 42 or 54 operate, and this is true likewise as to the portions of the upper operated upon by these members in lasting McKay shoes of the above-mentioned character. Accordingly the supply of tacks to the tack pockets in the members 26 or 52 may be cut off by the use of well-known means adapted for this purpose. There are, however, some other classes of work on which it may be desirable to use such yieldable members in operating on portions of the shoe where upperholding tacks are needed as, for example, shoes in which the uppers have surface ornamentation in the form of a band or strip extending upon the shoe bottom close to the heel seat and producing an abrupt thickening of the upper materials in locations near, if not actually on, the heel seat.
